52 Claims. I

This invention relates to machines for operating on shoes, and is hereinshown as applied to a toe-lasting machine constructed generally asdisclosed in United States Letters Patent No. 2,- 324,509, granted onJuly 20, 1943, on an application of mine, but modified in some respectsas further disclosed in other Letters Patent hereinafter mentioned. Itis to be understood, however, that in various novel aspects theinvention is not limited to the illustrative embodiment.

The above-mentioned lasting machine is a fluid-operated machineincluding wipers which in the course of a cycle of automatic operationsof the machine wipe the lasting margin of the toe end of the upperinwardly over an insole where it is secured to the insole by cement. Themachine comes automatically to a stop to permit the wipers to remain fora few seconds in pressure-applying relation to the overwiped margin ofthe upper while the cement is setting, after which it is again startedand completes its cycle, releasing the shoe. One object of thisinvention is to increase the output of the machine by reducing the timerequired for the wipers thus to dwell on the margin of theupper. To thisand other ends, there is herein shown, as an attachment on the machine,novel means to which the shoe is presented by the operator immediatelyafter the toe-lasting operation for further pressing the margin of theupper on the insole until the cement has more firmlyv set. This meanscomprises a pressing plate formed to overlie the marginal portion onlyof the shoe bottom, and a shoe rest arranged to engage the top of theforepart of the shoe and movable while the operator supports the shoe toforce it against the plate, the latter being flexible to permit it toconform to the contour of the shoe bottom. The shoe rest is thusoperated in response to the presentation of the shoe to the plate byfluid obtained from an accumulator which is charged by thefluid-pressure system of the lasting machine, the shoe when thuspresented closing an electrical switch which controls the circuit of avalveoperating solenoid. This circuit is broken automatically by thenext cycle of operations of the lasting machine near the end of thecycle to cause the shoe rest to release the shoe. To insure that theabove-mentioned switch, after it has been closed by the shoe, willremain closed regardless of any slight displacement of the shoe,mechanism is provided for subjecting it automatically to closing forceindependently of the shoe.

Since the lasted toe end of a shoe of ,the type herein shown usuallyneeds to be trimmed to remove surplus material from the marginal portionof the upper at a distance from the edge of the shoe bottom near the endof the toe, the invention further provides novel means arranged tocooperate with the above-mentioned pressing plate to accomplish thatresult. In the construction shown a cutter is moved bodily lengthwise ofthe shoe along the shoe bottom toward the end of the toe to trim oifsurplus upper material extending beyond the plate, the cutter being thusoperated by a cutter support which swings about an axis extendingwidthwise of the shoe but being movable relatively to the support andheld yieldingly in contact with the plate in the uppertrimmingoperation. Operative movement is imparted to the cutter support byfluid-pressure means to which, as herein illustrated, fluid isconveniently admitted from the fluid-pressure system of the lastingmachine in the course of the next cycle of operations of the machine. Inorder to dispose of the waste material removed from the upper theinvention further provides novel ejector mechanism, this mechanism beingoperated, in the construction shown, in response to return movement ofthe cutter support after the trimming operation.

The above and other features of the invention,

' including novel shoe-positioning means, novel means for guiding theshoe into position to be operated on, and various novel details ofconstruction and combinations of parts, will now be more particularlydescribed with reference to the accompanying drawings and thereafterpointed out in the claims.

As disclosed. in the previously mentioned Letters'Patent, thetoe-lasting machine herein shown is provided with a plurality offluid-operated instrumentalities which operateon the shoe in the courseof a cycle of power operations of the machine. As further disclosedespecially in Letters Patent No. 2,391,461, granted on'December 25,1945, on anapplication of'mine, the shoe is presented by the operatorwith the bottom'of the forepart of the insole in engagement with a plate2 (Fig. 1) provided with a spur'4 which enters an indentation previouslyformed in the insole to assist in positioning the'shoe in properrelation to the lasting instrumentalities. Substantially at thebeginning of the cycle of operations of the machine the shoe is clampedagainst the plate'2 by the upward movement ofa toe rest 6. Included inthe lasting instrumentalities are a toe former 8 which wipes the toe endof the upper heightwise-of the last andapair of wipers IE! which wipethe lasting margin of the toe end'of the upper'inwardly over an'insoleon Prior to such operation of the wipers, however, the margin of all butthe outer layer of the toe-end portion of the upper materials is trimmedoff by trimming meansidentifiedgenerally by the reference character l2(Fig. 4) and hot thermoplastic cement is applied to the-toe end of theshoe for securing the margin of the upper to the insole, thecement-applying means 'being identified generally by thereference'character Hi.

The trimming means and the cementapplying means are supported .on' acommon carrier l6 which is mounted to swing about a vertical axis tocarry the cement-applying means into shoe after the operation ofthethereon, such swinging movement of the carrier being effected by apiston l8 movable in a cylinder at to which operating fluid- .isadmitted through a pipe line 22. .After the marginof the upper has beenwiped inwardly over the insole by the wipers H] the machine to a stop tocause the wipers toremain a few seconds in pressure-applying .relationto the upper while the cement is setting. Thereafter the machine isagain started and completes its cycle, releasing the shoe.

. In addition to the piston 18 and the cylinder 20 associated with thecarrier devices for'operating former 8, the wipers l0, instrumentalitieswith which the machine is provided, the several devices being suppliedwith operating 25, there are provided fluid, preferably oil,

pipeline-.22; the tube having from the position in 'fiuid to the pipeline by a 55) engaging a lug on thearm.

swung by a spring '80 over the arm 64 to swing the latch 58 20 andcorresponding tothevalve 748 shown in "Letters "Patent No. 2,324,509,this valve and its operating mechanism being shown in detail in Fig. 13.The valve is a sleeve valve mounted to slide ion'attube 28in'communication at one end with the manifold 24 and at the other endwith the therein a partition 30 which'dividesone end portion thereoffrom the other. At one side of the partition are a plurality of ports'32 and at the other side thereof a plurality of ports 34. Formed in thevalve is an annular chamber 35 through which the ports 32 are caused tocommunicate with the ports 34. toadmit fiuid'from-themanifold 24 to thepipe valve is moved toward the left which it is shown in Fig. 13.The-valve is controlled through an arm 38 pivotally mounted at lfl on abracketAZ, a spring 44 line 22 .when the being connected'to this arm tomaintain the valve normally in positiontc prevent communication betweenthemanifold. and the'pipe line 22, as shown. The ports are uncovered atthat time to permit exhaust of fluid from the pipe line 22 back-toareservoir or sump 46. The arm 38 is swung into position'to cause thevalve to admit lever 63 also pivoted at 40 on the bracket42 and arrangedthus to act on the arm'38 through a small compression spring The lever48 is operatedat the proper time in the cycle by one of a plurality offingers 52 mounted on a rotatable drum 54 like that/shown in LettersPatent No. 2,337,558,'granted on December 28, 1943, on an application ofmine, the finger being arranged to engage aroll56 onone end ofthezlever. In this movement "of 'the lever a latch 58 .pivotally mountedthereon is carried into position to be a shoulder 62 on the bracket 42to retain the valve 25 in the position to which it is moved, the spring60 being connected to an arm'fid which isin fixed relation to theylatch. At the proper time in the cycle another-ofthe fingers'52 onthedrum 5A acts on from over the shoulder 62, whereupon the'spring 44returns the valve 26 to its initialposition.

The drum 54 is rotated-by fluid admitted to a cylinder-'66 (Fig. .14)from the manifold 24 and acting on -apistontfiflconnected to the drum,the

fluid being'admitted to the cylinder by a valve 10 movableby'the'operator'thus to start the cycle of operations'of the machine. Itwill be understood'thatthe cycle of operations corresponds thefluid intothe manifold I6. When-the machine is returns freely from through a valve18 not in operation the 'fluid the 'manifold tothe sump withoutdeveloping any substantial pressure in the manifold. operator to closeThe valve 13 is moved by the the outlet from the manifold before thevalve 10 is operat d to start the machine;whereuponpressure is developedin the manifold and the excess fluid delivered by the pumpreturns-to thesump 46 past a spring-controlled relief valve which determines thepressure in the manifold. At the end of the cycle of operations thevalve 18 is returned automatically to its initial position to cause thepressure in the manifold to'fall substantially to zero.

As thus far described. the machine herein shown may be assumed to beconstructed substantially as disclosed in the previously mentionedLetters Patent. As further disclosed in Letters Patent No. 2,420,665,granted on May 29, 1947, on an application of mine, it has attached toits right-hand side mechanism indi cated generally by the referencecharacter 82 (Fig. 1) for providing the insole with an indentation toreceive the previously mentioned shoepositioning spur 4, the shoe beingpresented to this mechanism before it is presented to the lastinginstrumentalities. The indenting mechanism is operated by fluiddelivered by the pump I2. In order to permit it to be thus operated whenthere is no pressure in the manifold 24, i. e., prior to the beginningof a cycle of operations of the lasting machine, there is provided anaccumulator 84 (Fig. 14) comprising a cylinder 86 in which is a piston88 movable against the resistance of a spring 90 by fluid admitted tothe cylinder. Fluid is conducted to the accumulator from the pipe lineI6 by a pipe line 92 in which is a check valve 94 to prevent return ofthe fluid. The fluid for operating the indenting mechanism is conductedto that mechanism from the accumulator through a pipe line 05. It willbe understood that the accumulator is charged at any time when themanifold 24 contains fluid under pressure greater than that of the fluidin the accumulator, and that when the pressure in the manifold isreduced to zero at the end of each cycle of operations of the lastingmachine the accumulator remains charged so that the indenting mechanismmay be operated when the lasting machine is idle.

For purposes of this invention there is conveniently supported on theleft-hand side of the frame of the lasting machine a toe-pressing andtrimming attachment identified generally in Figs. 1 and 4 by thereference character 08. One of the functions of this attachment is toapply pressure to the cement-lasted marginal portion of the toe end ofthe upper immediately after removal of the shoe from the lastinginstrumentalities to hold the upper on the insole until the cement hasmore firmly set, thus permitting the time during which the upper is heldunder pressure by the lasting wipers I to be shortened with a consequentincrease in the output of the lasting machine. To this end, theattachment includes a presser consisting of a plate !00 (Figs. 8 and 10)arranged to engage the lasted marginal portion of the upper overlyingthe insole, the plate having therein a recess I02 so that it will extendinward only over the margin of the shoe bottom about the end and alongthe sides of the toe. The plate is flexible to permit it to bend andthus to conform to the contour of the shoe bottom for applying effectivepressure to all portions of the upper beneath it. Beyond the end of thetoe and also along the opposite side margins of the plate the latter isthickened, its side marginal portions being inserted in horizontal slotsI04 (Fig. 11) formed in supporting members I 00 which are fast onopposite side frame plates I08 of the attachment (Fig. The plate I00 isheld firmly in the slots I04 by a setscrew H0. The shoe is presented bythe operator to receive the pressure of the plate by moving itlengthwise to a position where the marginal portion of the toe end ofthe upper overlying the insole is under the plate. To guard against anydamage to the shoe by contact with the front edge of the plate when itis thus presented, there are provided two tapered rolls II2 mounted toturn on studs 4 which are supported on the front ends of leaf springsIIG secured at their rear ends by screws II8 on the tops of the membersI06, the rolls 'being arranged to engage respectively the opposite sideportions of the shoe bottom. Initially the lower faces of the rolls aresomewhat lower than the plate, as shown in Fig. 5, but after the shoehas been properly presented the leaf springs II6 are yieldable to permitthe rolls to be lifted by the shoe when the shoe is forced upwardagainst the plate. To position the shoe laterally in proper relation tothe recess I02 in the plate I00, there are provided two leaf springs I20arranged to extend rearwardly in converging relation to each other toreceive and to centralize the toe end of the shoe between them by theirengagement with the sides of the toe. Each of these springs is securedagainst the inner vertical face of one of the members I06 by the flangedinner end of a sleeve I22 (Fig. 8 which extends outwardly through a slotI24 formed in the member I06 and in the frame plate I08, a hand wheelI26 being threaded on this sleeve and engaging a washer I28 which bearson the frameplate. It will thus be seen that by turning the hand wheelin one direction the spring I20 is clamped firmly against the memberI06, and that upon turning the hand wheel reversely the spring isloosened to permit'it to be adjusted in directions lengthwise of theshoe by moving the sleeve I22 along the slot I24. Fast in the inner endportion of each sleeve I22 is a small sleeve I30 in which is threaded ascrew I32 in engagement at its inner end with the corresponding springI20. By turning the two screws I32, therefore, the shoeengaging portionsof the springs I20 may be adjusted in directions widthwise of the shoeas may be required for shoes of different widths.

After the shoe has been presented as above described it is forcedupwardly against the plate I00 by a shoe rest I34 engaging the" top faceof;its toe-end portion. This shoe rest is supported on the upper end ofa piston I36 (Figs. 5 and 6) movable vertically in a cylinder I38 whichis part of a casting I40 (Fig. 7) secured to a horizontal frame plateI42. Springs I44 connected to pins I 46 which extend from the pistonthrough slots I 48 in the cylinder I38 hold the piston initially in itslowest position determined'by' engagement of the pins with the cylinder,the lower ends of the springs being connected to studs I50 threaded inthe frame plate I42. Fluid is admitted to the lower end of the cylinderI38 and is later exhausted therefrom through a port I52 in the castingI40 under control of a horizontal slide valve I54 in the casting, thisvalve having an annular recess I56 in communication at all times withthe port I 52. When the valve is in its initial position, asshown inFig,7, this recess is in communication alsowith an exhaust port I58 fromwhich a pipe I60 leads to a point over the sump 46 to permit return ofthe fluid to the sump. Operating fluid is admitted to the cylinder I38to cause the shoe to be forced up against the plate I00 by movement ofthe valve I54 to a position in which an inlet port I62 in the casting"I40, instead of the exhaust port I58, is in communication with the portI52. Since the cycle of operations of the lasting machine has beencompleted at the time when the shoe 'is forced up against agar-no.6

This; mechanismincludesa trimming knife or cutter 234 mounted ona holder 236 which issupported by downwardly and forwardly extending'arms 23B of. twobell-crank levers 240 mounted to swing about a rod 242 supported by theframe plates I08 and extending widthwise of the shoe, the two bell-cranklevers being rigidly connected together by a web 244 To operate thecutter 234 the bell-crank levers are swung in a clockwise direction withreference to Fig. 6 by means hereinafter described. The holder 236 ispivotally mounted on studs 246 (Fig. 5) on the ends of the arms 238' toswing relatively to the arms about an axis extending widthwise of theshoe and it is engaged by two spring-pressed plungers 248 carried by thearms 238, these plungers tending to swing it in a counterclockwisedirection and holding it initially in contact wi lus 2. .9 on. th armas. shown i i 6.

Itwillfbeunderstood that in this operation theplateholds-portions of theupper of the 9 adjacent to the line of the outagainst the thrust of the cutter.

For swinging thebell-crank levers 240 to operate the cutter in themanner above described rearwardly extending arms 2 54 of these leversare connected by links 256 to a crossbar 258 (Figs. 5 and 6) fast on theupper end of a piston 260 vertically movable in a cylinder 262 fast onthe frame plate I42. Springs 264 connected to the crossbar and to studs266 in the plate I42 tend to move the piston downwardly and hold thebell-crank levers 240 normally in their initial positions determined byengagement of a pin 268 in the piston with the cylinder 262 at the lowerends of slots 210 in the cylinder. .The'limit of the upward movement ofthe piston and of the operative movement of the cutter is furtherdetermined by engagement of the pin with the cylinder at the upper endsof the slots. Conveniently the piston 260 is operated at a predeterminedtime in the next cycle of operations of the lasting machine after thepreviously lasted shoe has been clamped against the plate I by the toerest I34,

I and for this purpose operating fluid is conducted to the cylinder 262by a pipe 212 (Figs. and 14) leading from the previously mentioned pipeline 22 to which fluid is admitted by the valve 26 for swinging thecarrier I6 to bring the cementapplying means I4 into position over theshoe after the trimming of the inner layers of the upper materials bythe trimming means I2. After the cutter 234 has been operated it remainsat the limit of its operative movement until, in the course of the cycleof operations of the lasting machine, the valve 26 is returned intoposition to release the fluid from the pipe line 22, Whereupon thepiston 260 is moved downwardly by the springs 264 and the cutter isthereby returned to its initial position.

The cutter 234 is inserted in the holder 236 by sliding it into grooves214 (Fig. formed'in the holder. Its position with respect to the holderis determined by a screw 216 (Fig. which is threaded in the holder andis provided with a flange 218 extending into a groove in the cutter. Bymeans of this screw the cutter may be adjusted along the grooves to varythe position of its cutting edge relatively to the previously mentionedfingers 252 (Fig. 5).

To dispose of the waste material received from the upper by the cutter234 there is provided an ejector 286 (Fig. 10). As shown further in Fig.9, this ejector includes an inclined plate 282 positioned normally withits lower edge in engagement with the top of the cutter 234 in a recessin the holder 236. Extending from this plate is an arm 284 pivotallymounted on a pin 286 carried by an arm 288 which is mounted to swingabout the previously mentioned rod 242 between the bell-crank levers240. A spring-pressed plunger 290 in the arm 288 engages the arm 284 andholds the plate 282 down on the cutter 234. The arm 238 is connected bya link 292 to one arm 294 of a bell-crank lever 296 mounted to swingabout a rod 298 which provides the connection between the arms 254 andthe links 256. A spring 300 connected to the arm 294 and to a pin 302 inthe web 244 holds the arm 288 initially in a position determined by theengagement of a screw 304 mounted in a lug 306 on the hub of the armwith the web 244. By the cutteroperating movement of the bell-cranklevers 240 the bell-crank lever 286 is carried upwardly to a ositionwhere an arm 308 thereof extends over the upper end of a pawl 3| 0pivotally mounted on a pin 3I2 which is supported by a block 3I4 fast onthe frame. A spring-pressed pin 3I6 in the block holds the pawl normallyin a position determined by engagement of a tail portion 3; thereof witha screw 320 in the block. Accordingly, in response to the returnmovement of the bell-crank levers 240 after the trimming operation thebell-crank lever 296 is swung by the pawl 3l0 in a clockwise direction(Fig. 12) and thereby swings the arm 286 to carry the plate 282rearwardly from over the cutter 234 and along the top of the plate I00to move the waste material into a trough 322 (Fig. 8) arranged toreceive it. This trough includes .a horizontal plate 324 secured to theframe plates I06 in the same plane as the presser plate I00, andupstanding side plates 326 the front end portions of which are curvedoutwardly away from each other and extend over the presser plate I80.Preferably the trough 322 extends rearwardly and downwardly to aposition over the top of a receptacle (not shown) with which the machineis provided to receive the waste material removed from the upper by thetrimming means I 2 (Fig. 4) as disclosed in Letters Patent N6.2,324,509. It will be understood that successive increments of wastematerial in the trough 322 are pushed along the trough toward thereceptacle by the ejector 280. It will further be understood that in thecourse of the return movement of the bell-crank levers 240 after thetrimming operation the arm 308 of the bell-crank lever 296 slips ofi theend of the pawl 3I0, whereupon the spring 300 returns the arm 288 andthe plate 282 to the positions determined by engagement of the screw 304with the web 244.

The shoe is released by the shoe rest I34 near the end of the cycle ofoperations of the lasting machine. For this purpose there is fast on thedrum 54 a ring 328 (Figs. 2 and 3) carrying a screw 330 the head ofwhich is arranged to engage a lever 332 pivotally mountedat 334 on abracket 336 fast on the frame of the machine, the bracket supporting aswitch box 337. The lever 332 engages a plunger 338 movable in theswitch box and bearing against a resiliently flexible member 340 whichcarries one of the con,- tact elements of a switch 342 in the circuit ofthe solenoid I 66. The switch is operated to break the circuit by theaction of a screw 330 on the lever 332, whereupon the valve I54 (Fig. 7)is returned to exhaust position by the springs I88 and the shoe rest ismoved downwardly by the springs I44, releasing the shoe. Prior to theend of the cycle the screw 330 releases the lever 332 the returnmovement of which is limited by engagement of a screw 343 in its lowerend with the switch box. This causes the switch 342 again to close, butat that time the switch 2I6 (Fig. 6) is open by reason of the release ofthe shoe and the return of the piston I36. When the shoe is thusreleased and falls it is caught and held by a shoe receiver 344comprisinga pair of downwardly inclined rods 346 secured at their upperends to the frame plates I08, the rods having thereon diverging wings348 between which the shoe is receivedand being provided at their lowerends with a pad 350 for engaging the heel-end face of the shoe. 7

To avoid the necessity of running the lasting machine idly through acycle of operations in order to cause the cutter 234 to operate on thelast shoe, there is provided means whereby the operator may move thevalve 26 (Fig. 13) manually toadmit fluid from the manifold 24 to thepipe line 22. This means comprises a wire 352 guided by a flexible cable354 and connected at one end to the valve-operatinglever 48, the otherend of the wire being connected to a pin 356 slidingly movable in afront frameplate 358 and having fast on its outer end a knob 366. Aspring 362 mounted between the frame plate and a member 364 fast on thepin 356 holds the knob 366 normally against the front of the frameplate. To cause the cutter 234 to operate on the last shoe the operatorulls on the wire 352 by means of the knob 366, thus moving the valve 26into position to admit fluid to the pipe line 22. 'The member 364 is soadjusted on the pin 355 that by engagement with the frame plate 358 itprevents the lever 48 from being moved far enough to cause the latch 58to swing inwardly over the shoulder 62. After the operation of thecutter the operator releases the knob 366, whereupon the valve 26 isreturned to its initial position and releases the fluid from the pipeline 22 to cause return movement of the cutter. It will be understoodthat the movement of the valve 26 results also in anidle-swinging-movement of the carrier I6 (Fig. 4). Since the pressure inthe manifold 24 falls substantially to zero upon the completion of eachcycle of operations of the lasting machine, the operator, beforeoperating the valve 26 as above described,.moves the valve 1.3 (Fig. 14)into position to close the outlet from the manifold and thus to causethe development of pressure therein as he normally does prior tostarting each cycle of operations. After the op-- eration ofthe. cutterand .the. return of the valve 26 to its initial position the operatorcauses the valve I6 toreturn andto release the fluid from the manifoldby movement of amember not herein shown with which the machine isprovided, this member being that identified by the reference character1214 in Letters ,Patent No. 2,324,- 509. In order to cause the releaseof the last shoe after .it has .been trimmed the operator breaks thecircuit of the solenoid I66 bya hand switch (not shown) mounted inaswitch box 366 (Fig. 5) and controlled by .a handle .366.

The operations hereinbeiore described, in so farv as they are of specialinterest with reference to the present invention, will now be brieflysummarized. Itwill be understoodthat in the course of the cycle.ofoperations of thelasting machine the toe end .of .the shoeis lastedinthe same manner as heretofore, except that the wipers I6, after wipingthemargin of the upper inwardly over the insole, remain for only acomparatively brief time in pressure-applying relation to the upper.Immediately uponrelease of the shoe at the end of the cycle theoperatorpresents it to thepressing and trimming attachment96, moving itlengthwise under the guidance .of the rolls H2 into position beneath thepressing plate I66 until its toe-end face presses against the pad 262.The pressure of the shoe on this pad operates the switch 2I6 (Fig. 6) toclose the electrical circuit of the solenoid I66, thus causing the valveI54 to be moved into position to admit operating fluid from theaccumulator'84' to the'cylin'der I36. By the fluid thus admitted to thecylinder the shoe rest I34 is moved upwardly to force the shoe firmlyagainst the plate I66, the latter bending more or less to conform to thecontour of the shoe bottom. In this operation the spring 232 iscompressed toinsure thatthe switch 2I6 will remain closed. The operatorthen presents the next shoe to the lasting instrumentalities-and againstarts the cycle of operations of the lasting machine. At

12 cycle'when the valve 26 is'oper ated to. admit fluidto .thepipe line22:and' thusxto cause. the carrier'16 '(Fig. 4) to beswung .intoposition, to bring thecement-applying means I4 over'the shoe, fluid'fromthe'same pipe line 22 is admitted to the cylinde'r'2B2 'to operatethe cutter 234. .As thefcutter'is operated'through'the bell-crank lever246 .it receives "first a compo-' the time in that nent of downwardmovement toward the plate I66, the members 252 (Figs. '5 and 9) engagingthis plate and causing'the Jcutterholder 236 .to swing about thestudsf246 onthe arms 238. "In this manner the cutteriscaused to assumeaposition.morenearlyparallel'to,the plate I66, and as itis.moved.'farther lengthwise of the shoe toward the end of the toe itscutting edge engages the top of the plate and trims off'the surplusmarginof'the upper extending inwardly and upwardly beyond v.the plate(Fig. 10), the operative movement .of'the .cut'terbeing limited byengagement of the,p'in 2.68 withlthe cylinder 262 at the upperen'dsofithe s'lotsi2'l6'. .Near'thet'end oithe operativemovement oilthecutter'the arm.368 of the bell-crank lever296'is carried upwardly pastthe yielding paw13'I6 andt'hepawl snaps inwardly undenthe .arm. 'At'th'etime ;intthe cycle of operations of the lasting machine when the fluidisreleasedffrom the pipe line 22' by return movement oflthe valve, 26.the belle rank levers 246 arereturneld'by thesprings 264 acting on thepiston 266. "Early in this return movement of the bell-'crank'leversanidfthe cutterthe pawl .3116 causes"thebell-crankflever 296'to swing inthe direction tooperate the eiector2'86 (Fig.'12) ,.thus causing theejector to force the waste material removed. 'fromjthe upper over 'theplate "I 66 andinto thetroughj322'by which the successive'increments ofwaste material removed-from the .difierentshoes are conducted to awastareceptacle (notshown). .Asthe bell-crank levers 246;contimie their.return'movement the arm 36B slips. off the,pawl-3I6, whereuponthespringi366 returns the .eiector266 toji'tsii'nitialposition with respect.to thecutteriholder 236. Near the end of the-.cyCleOiopertionsofthe'lasting machine the. screw -33.6 (Fig.3) .acts .on thelever332 to openthe. switch 342,;thusbreaking the electrical circuit ofthe solenoid I66 and causing the ,valve I54 toreturnto itsinitialposition and to release the lfluidfromthecylinder I38. vIThe shoe restI34 is thenreturned by the springs I44, thereby releasing the shoewhichfalls and is caught and held .by the.shoe..receiver'344. Justbefore ,the completion of the .cycleof the lasting machine thescrewl'336rpasses'beyond the lever.332, causing theswitch 342againtoclosepthe switch 2 I6 being thenopen. Accordinglythe pressing andtrimming attachment is ..in.condltion to receive the next shoeimmediatelyupon its release by the lasting machine, .,To causethecutter234 to operate on the'last shoe when the-lasting machine is idle, theoperator .manipulates the valve 26 by means of the wirei35'2 (Fig. 13),after he.has closed the .valve. 'l8-to-cause pressure to develop inthemanifold 124, .andafter the operation of theciitter he again .opensthe valve 16. "T0. cause the shoe rest I34 to,releaseathelastrshoe he.breaks theclrcuitof the solenoid I66 by means .of the handle368 (Fi 5)on the swltch'box'366.

It will'be understoodlthat although the shoe remains under'the pressureof the lasting wipers a substantiallyshorter time than heretofore, thelasted marginof the .upper is held effectively enough inlastedpositionby the cement in the brief interval before it is subjected'to thefurtherto cause the presser to pressure of the pressing plate I00. It will beevident that the margin of the upper is normally held by this plateuntil the next shoe is presented to the lasting machine andsubstantially throughout the next cycle of operations of the machine,during which time the setting of the cement is completed to cause it tohold the upper securely.
